如何剪裁XLD

我用的是一个Rectangle2建立的Roi，然后根据region生成的XLD
但是生成XLD的时候他会把边缘当成线，如何把这个边缘去掉呢，我发现halcon中有Clip_xxxx, crop_xxx算子，但是这些算子的剪裁区域都只是rectangle1类型，不支持rectangle2，像我这种情况如何才能把边上的直线剪裁掉呢

1. read_image (Image2, 'C:/Users/Administrator/Desktop/ImageSaved/2.jpg')
   
2. dev_close_window()
   
3. dev_open_window_fit_image(Image2, 0, 0, -1, -1, WindowHandle)
   
4. dev_display(Image2)
   
5. draw_rectangle2(WindowHandle, Row, Column, Phi, Length1, Length2)
   
6. dev_set_draw('margin')
   
7. gen_rectangle2(Rectangle, Row, Column, Phi, Length1, Length2)
   
8. 
   
9. reduce_domain(Image2, Rectangle, ImageReduced)
   
10. 
    
11. threshold (ImageReduced, Regions, 163, 255)
    
12. 
    
13. gen_contour_region_xld(Regions, Contours, 'border')

如下图

哪位大哥帮忙看下，这个问题一直很困惑，我觉得halcon肯定是有其他办法的，但是我不知道怎么处理

思路是用生成的旋转矩形中心和角度先来旋转轮廓和矩形，然后裁剪完之后，再旋转回去

1. read_image (Image, 'E:/halcon学习/Learning/ArcLine.png')
   
2. dev_close_window ()
   
3. dev_open_window_fit_image (Image, 0, 0, -1, -1, WindowHandle)
   
4. dev_display (Image)
   
5. threshold (Image, Region, 0, 100)
   
6. gen_contour_region_xld (Region, Contours, 'border')
   
7. gen_rectangle2 (Rectangle, 119.204, 114.615, rad(27.1565), 66.5368, 62.0099)
   
8. hom_mat2d_identity (HomMat2DIdentity)
   
9. vector_angle_to_rigid (119.204, 114.615, 0, 119.204, 114.615, rad(-27.1565), HomMat2D)
   
10. affine_trans_region (Rectangle, RegionAffineTrans, HomMat2D, 'nearest_neighbor')
    
11. affine_trans_contour_xld (Contours, ContoursAffineTrans, HomMat2D)
    
12. smallest_rectangle1 (RegionAffineTrans, Row1, Column1, Row2, Column2)
    
13. clip_contours_xld (ContoursAffineTrans, ClippedContours1, Row1, Column1, Row2, Column2)
    
14. hom_mat2d_identity (HomMat2DIdentity)
    
15. vector_angle_to_rigid (119.204, 114.615, 0, 119.204, 114.615, rad(27.1565), HomMat2D)
    
16. affine_trans_contour_xld (ClippedContours1, ContoursAffineTrans1, HomMat2D)
